MOSES MOSLER, OF CINCINNATI, OHIO, ASSIGNOR TO THE MOSLER SAFE COMPANY, OF NEV YORK, N. Y.

SAFE.

SPECIFICATION forming part of Letters Patent No. 575,306, dated January 12, 1897. Application filed August 21, 1896. Serial No. 603,438. (No modelfl To all whom it may concern.-

Be it known that I, Mosns MOSLER, of Cincinnati, Hamilton county, Ohio, have invented certain new and useful Improvements in Burglar-Proof Safes, of which the following is a specification.

There is in common use a class of burglarproof safes consisting of a shell of drill-proof material provided with an inwardly-openin g door, the door being arranged to move inwardly to free it from its jambs and then turn upon a vertical axis to carry it to the rear of the chamber within the shell, the treasure-receptacle turning with the door and coming to the opening in the shell as the door takes its position of retreat.

My invention pertains to improvements in this general class of safes, and my improvements will be readily understood from the following description, taken in connection with the accompanying drawings, in which- Figure 1 is a vertical axial section, plane of line a of Fig. 2, of a safe exemplifying my invention, the parts being in the position corresponding with the closed and locked position of the safe; Fig. 2, a horizontal section of the same in the plane of line b of Fig. 1, the interior parts appearing in plan, the door being in condition of retreat from its jamb to permit the inner structure to be turned; Fig. 3, a view similar to Fig. 2, but with the inner structure turned through an angle of ninety degrees; Fig. 4, a similar view, but with the inner structure turned through an angle of one hundred and eighty degrees to bring the treasure-compartment to the front; Fig. 5, a vertical section, plane of line 0 of Fig. 1, of a portion of the shell and showing a portion of the door in rear elevation and in locked condition; Fig. 6, a front elevation of the treasure-chest; Fig. 7, a plan of door and treasure-chest, a portion of the latter appearing in horizontal section in the plane of line b of Figs. 6 and 8; and Fig. 8, a side elevation of the treasure-chest. Figs. 6, 7, and 8 are on a smaller scale than the remainder of the figures.

In the drawings, referring for the present to Fig. 1, 1 indicates a shell of drill-proof material and provided at its front with a circular opening or door-jamb, which opening ward; 5, a screw projecting concentrically from the inner face of the door and having a pitch corresponding with that of thread 4 6, a yoke-disk supported within the shell parallel with the rear face of the door when the door is in closed condition, as in Fig. 1; 7 a nut at the center of this yoke-disk and e11- gaged by screw 5, so that as the door is unscrewed inwardly on its threads 4 it becomes supported by screw 5 in the yoke-disk; 8, a pair of vertical pintles carried by the yokedisk and engaging the shell and forming the axis of rotation of the inner structure of the safe; 9, a treasure-chest formed by a casing carried by the yoke-disk and extending rearwardly therefrom into the rear of the shellchamber, and 10 a doorway in the rear wall of treasure-chest 9.

Viewing Fig. 1, the only figure of the drawings thus far considered, it will be observed that door 2 is seated in its jamb, tightly fitting at seating 3, and firmly held by threads 4. To remove the door outwardly would require force sufficient to burst the shell. To remove the door directly inwardly or to turn it orbitally would require force sufficient to strip threads 4 and 5 and break the yoke. It follows that the door can be unseat-ed only by unscrewing it inwardly from its jamb.

By unscrewing the door inwardly it retreats toward yoke-plate 6 and disengages threads 4 and seating 3, leaving the parts in the posidition of the safe. To close the safe the inner structure is turned back to the position indicated in Fig. 3, and then to the position indicated in Fig. 2, and the door is then to be screwed outwardly till home and in the position indicated in Fig. 1.

\Vhen the safe is closed, its locking is effected by automatic time-lock mechanism disposed entirely within the safe and having no communication with the exterior of the safe. Locking mechanism of an exemplifying character will now be described.

Referring further to the drawings, 11, Fig. 5, indicates a notch cutin the interior thread 4 of the shell; 12, a recess in the inner face of the door in a position corresponding with the locality of notch 11, that is to say, when the door is screwed home, recess 12 will come I at notch 11; 13, a pawl pivoted to the door in recess 12, its point engaging in notch 11 1 against the end of the shell-thread formed by the cutting of that notch, the direction of action of the pawl being such that the pawl engaging the end of the shell-thread at the notch prevents the unscrewing of the door; 14, a flexible lever projecting from the pawl, this lever being a spring with its free end extending rearwardly and lying against the front face of the yoke-plate, as indicated in Fig. 7 g 15, a pin projecting rearwardly from the end of lever 14; 16, a concentric groove in the rear face of yoke-plate 6, this groove being engaged by pin 15, the radial position of the groove being such as corresponds with the position of pin 15 when pawl 13 is inward out of engagement with the shell-thread; 17, the time-lock, of any ordinary construction, disposed in one side of the treasure-chest at a suitable opening in the side wall thereof, and 18 a block sliding radially in a groove in the rear face of yoke-disk 6 and having in its front face a segment of groove 16, the timelock serving to operate this block and move it outwardly so that the groove in the block coincides with groove 16 in the yoke-disk, or to move it inwardly into the position indicated in Fig. 6, in which position the groove in the block. corresponds with the position of pin 15 when pawl 13 is engaging the shellthread.

Block 18 is in such angular position on yoke-disk 6 as corresponds with the position of pin 15 when the door is closed and pawl 13 in engagement with the pawl-thread. In this condition the time-lock is inert and the safe is locked by the pawl. At the proper time, as controlled by the setting of the timelock, block 18 moves outwardly, carrying pin 15 to the radial position of groove 16. This motion of the block unlatches the pawl from its notch and permits the door to be unscrewed, in the course of which unscrewing motion pin 15 travels around in groove 16, the flexing of lever 14 compensating for the approach of the door toward the yoke-disk. When the safe is to be closed, the door is screwed home and the time-lock moves the pawl to latching position, where it remains till the predetermined time of opening arrives.

lVhen the inner structure is in the halfway position indicated by Fig. 3, then timelock 17 becomes presented at the front of the safe, giving convenient access forsetting, &c. 'lheimproved safe may have any or all of the usual adjuncts of safes of this character. Thus, for instance, the structuremay be provided with a supporting-bases. The exterior of the door maybe provided with day-locking attachments, as is common in screwdoorsafes dependent on isolated interior looking devices for their burglar-proof locking security. The treasure-chest maybe divided into interior compartments and have a door at its opening 10. Forsmall safes the screwdoor may be turned by a suitable implement applied at the non-circular socket indicated in Fig. 1. For large safes gearing may be applied to the door as is usual in large screwdoor safes.

The shell of the safe may be formed of the material and in the manner usual in safes of the above generally described character.

I claim as my invention- 1. Ina safe, the combination, substantially as set forth, of a shell havinga threaded circular door-opening, a yoke mounted on pintles within said shell, and a door carried by said yoke and adapted for movement to and from the yoke and having a threaded periphery adapted to engage the threads of the door-jamb by screwing outwardly into the same.

2. In a safe, the combination, substantially as set forth, of a shell havinga circular doorjamb provided with threads and having a tapering seat enlarging inwardly, a yoke mounted on pintles within the shell, and a door carried by said yoke and having its periphery provided with threads and a seating adapted to engage said jamb.

In a safe, the combination, substantially as set forth, of a shell having a circular doorjamb provided with a tapering thread enlarging inwardly, a yoke mounted on pintles within the shell, and a door carried by said yoke and having its periphery provided with a tapering screw to fit the threads of said jamb.

4. In a safe, the combination, substantially as set forth, of a shell having a circular threaded door-jamb, a door having its periphery provided with threads to engage said door-jamb by screwing outwardly thereinto, a yoke supported on pintles within the shell, and a screw projecting centrally from the door into engagement with said yoke and having a thread corresponding in pitch with the thread on the jamb.

5. In a safe, the combination, substantially as set forth, of a shell having a circular doorjamb of tapering character enlarging inwardly, a yoke supported on pintles within the shell, a rotary door connected with said yoke and having its periphery formed to fit said jamb, and a screw upon said door adapted to move the door inwardly from its jamb as the door is turned upon the axis of such screw.
